FASTENING DEVICE FOR CABLES.v

Application filed June 19, 1922. Serial No. 569,222.

vices for Cables, of which the following is'a specification, referencebeing had to the accompanyingdrawings. v

This invention relates to locking devices and more particularly tolocking devices for flexible members, such as cables.

An object of the invention is to provide a device ofthis characterwherein the ends or' one end of a rope or cable may be positively lockedand firmly held, regardless of the I strain applied to the cable orrope,

Another object of the invention is to provide a locking device: of thischaracterin eluding a clamp carried by one port-ionof a cable and stopmeans carried by another cable or opposite end of the cable to which theclamp'is connected, saidstop 'member, being adapted to engage the clampto prevent slipping of the cable within the clamp. It is a furtherobject of the invention to provide a device of this character includinga clamp adapted to be carried by one end of the cable, the clamp havingjaws and a clamping lever, said jaws being adaptedto receive theopposite end of the cable, the I jaws beingurged into 'engagementwithsaid opposite end of the cable by the clamping lever, and means carriedby the opposite end of the cable for preventing longitudinal movement ofsaidopposite endof the cable. It is still a further object of theinvention to provide a locking device of this character including aclamp, the jaws ofwhich are normally urged toward each other intoclamping engagement with an object upon movement of the locking lever ofthe clamp to its closed position, said lever being; provided with meansfor securing the same tothe clamp in its lockedposition.

. lVith theseand other objects in view, the

inventionconsists in the improved construction and arrangement of partsto be hereinafter more, particularly described,v fully- :tasteningdevice constructedQin accordance with an embodiment of the inventionFigureQ is an end elevation partly closed; y Figure 8 is a section 3-3'of Figure '1; j s

Figure 4 is a plan view of the clamp in its open positionl f Referringto the, drawings, 5 designates a flexible member or cable which-"may becon- .struct'ed, ofany material. is of course obvious that portions ofthis device may be used o'n'a' single cable orfsepa'rate cables,ac-.cording" to the work. I illustration, however, the'device' is shown on asingle cable. In connection with the cable,

of the'clamp taken thev line i For the purpose of i a clamping deviceis' used, said clampi 1 H vice comprising a body member, consisting of asheet of resillent metal stamped to provide a body'member 6," having anextension 7 projecting front one side, there- 7 of. The side portions 8and 9 of'th'el body member" serve as jaws, the jaw 8 havspacedextensions 10' projectingtherefrom, said. extensions being coiled to provide hinge knuckles, the knuckles projecting beyond the edge of the jaw9. In'the forma} tion. oftheclamp of the lock, the body memher is bentat' its central portion to provide a socket memberi ll substantiallycorresponding in" diameter to the diameter of the cable or flexiblemember to bec'lamped' and adapted to receive one endlot thecable, Theextension? has its marginal edges-separated from thejaws '8' and 9 sothat said extension may be formed into a ferrule or sleeve adapt ed toreceive the extremity of thecable 5. Brazing, soldering, .or anysuitable means may be used to firmly secure theextremity of the cablewithinthe ferruleor sleeve.

By this formation, the jaws 8 and, 9 are disposedinspaced parallelrelation to each other and as the clamp is made of resilient metal, the.jaws are intended to .be normally sprung away from each other and alsoeat tend a considerable distance outwardlyof the secured end ofthecable. .In order to urge the jaws toward each other-and to dis.-

pose the same in their clamped position, a

clamp lever 12 is provided, saidvlever' con sisting of a length ofresilient material having one end portio 13 thereof reduced to providean extension. The extension is coiled to form a hinge knuckle 14:adapted to be disposed between and register with the openings of thehinge knuckles formed by the extensions 10. The lever is then bentadjacent its end portion 13 substantially at right angles to said endportion, while the opposite end portion 15 is likewise bent in angularrelation to the central portion of the lever, the last bent portionbeing curved according to the diameter of the socket 11. The extremityof the end portion 15 is provided with a bead 16 which not only formsthe finger piece, but assists in locking the lever in a manner to behereinafter described. The knuckle 14 is pivoted by means of a pintle 16passing through the hinge knuckles of the jaw 8. The end portion 13,that is, that portion of the lever from the hinge knuckle 14 to thejunction of the central portion with the end portion 13, is considerablyless in length than the distance between the upper edges of the jaws 8and 9 so that when the lever 12 is swung over the jaw 9, said jaw willbe urged toward the jaw 8, because of the shortness of the end portion13 as above described.

In view of the fact that the jaws are normally swung outwardly, when theend portion 15 of the locking member is engaged with the bottom of thesocket member 11, the jaw 8 likewise will be urged toward the jaw 9 asthe end portion 15 is inclined inwardly toward the central portion ofthe lever. This naturally causes both jaws to bind on the cable byurging both jaws simultaneously toward each other. This locking actionis assisted by the bead 16 as it reinforces the end 15 and prevents thesame from springing out wardly. Furthermore, when the lever is swung toits closed position, the end portions 15 will urge the end portions 18into engagement with the upper edge of the jaw and through thecooperation of the contact of the end portion 13 with said jaw and thefrictional engagement of the end portion 15 with the body member 6,accidental movement of the lever is prevented. To permit all possiblestrain to be applied to the cable clamped by the jaws 8 and 9, theopposite end .ofthe cable 6 is provided with stop members 17, said stopmembers being constructed in the form of rings which are clinched orotherwise secured to the cable in spaced relation to each other, thespace between the stop members corresponding to the width of the jaws 8and 9. Any number of these stops may be used, according to the varietyof adjustment desired.

In operation of the device the end of the cable provided with the stops1'? is placed between the jaws 8 and 9 so that one stop is disposed ateach end of the jaw and adapted to engage said jaws. The lever 12 isthen swung over tlre end of the cable to be secured and looked as abovedescribed. This firmly holds the end of the cable within the clamp.However, should abnormal strain be applied to the cable, the stopmembers will come in contact with the ends of the jaws and there bylimit or prevent longitudinal movement of the cable and prevent breakingof the grip of the jaws on the opposite end of the cable.

From the foregoing it will be readily seen that this invention providesa novel form of fastener capable of being used any place desired toconnect two ends of a cable to each other, or wherein it is desired toconnect two cables. It is especially recommended for use in connectionwith the side conecting members of automobile anti-skid devices, as itprovides a lock which is compact and which can be readily operated andadjusted to suit the size of the wheel. All of these features arepossessed by a device that is exceedingly simple in construction andpositive in its locking action.

What is claimed is 1. In combination with a flexible member, a clampcarried by one end of said member, stop members carried by the oppositeend of the flexible member in spaced relation to each other, said clampbeing arranged to re ceive and clamp the second mentioned end portion ofthe cable, said stop members preventing movement of the second mentionedend portion of the cable from its clamped position within the jaws.

2. A fastening device comprising a clamp including a pair of resilientjaws, a lever carried by the end of one of said jaws and adapted toextend over the end of the opposite jaw for urging said jaws toward eachother, a flexible member having stop rings, carried by its end ortion inspaced relation to each other, one of the portions of said end portionbetween said rings being adapted to engage the jaws of the clamp, thelever of said clamp being adapted to urge the jaws into bindingengagement with said portion of the cable, the stop rings of saidportion of the cable being arranged to engage the end portions of theclamp to prevent longitudinal movement of said cable in eitherdirection.

In combination with a cable, stop rings carried by one end portion ofsaid cable, said rings being spaced from each other longitudinally ofsaid end portion. a clamping device consisting of a resilient sheet ofmaterial bent to provide a pair of jaws, said sheet having an extension,the extension being formed into a ferrule adapted to receive theopposite end of the cable, means for permanently screwing said oppositeend of the cable within the ferrule, a substantially U-shaped clampinglever pivoted to one of said jaws and adapted to extend over theopposite jaw. said jaws being adapted to receive the portion of thefirst mentioned end of the cable disposed between said rings to preventdisengagement of the stop rings from the jaws and to clamp said jaws inengagement with the first mentioned end of the cable.

&. In combination With a flexible member, a clamp carried by one end ofsaid member, stop members carried by the opposite end of the flexiblemember in spaced relation to each other, said clamp being arranged torecelve and clamp the second mentioned end portion of the cable, saidstop members pre-- venting movei'nent or" the second mentioned endportion of the'cable in either direction from its clamped positionbetween the jaws; e

In testimony whereof I hereunto affix my signature. 7
